a building that is 20 meters tall casts a shadow that is 5 meters long. at the same time a tree casts a shadow that is 8 meters long. how tall is the tree?

Solution

The general form of the equation is y = mx + b, where m is the slope and b is the y-intercept.

Given: m = 8/7 and b = -3

Plugin the given values into the formula.

y = 8/7x - 3

The answer is y = 8/7x - 3

Thank you :)

The correct equation representing the line with a slope of negative 8/7 and a y-intercept of negative 3 is y = -8/7x - 3. This was determined by substituting these values into the slope-intercept form of a line equation, y = mx + b.

The equation of a line in slope-intercept form is given as y = mx + b, where m is the slope of the line and b is the y-intercept. In this case, we're looking for an equation with a slope (m) of -8/7 and a y-intercept (b) of -3.

Substituting these values into the slope-intercept form, we get: y = -8/7x - 3.

So, the correct answer is y = -8/7x - 3.

You run 0.5 miles every 3 minutes => 1 mile every 6 minutes. Your friend runs 2 miles every 14 minutes => 1 mile every 7 minutes. You run a whole number of miles every number of minutes that is a multiple of 6. Your freind runs a whole number of miles every number of minutes that is a multiple of 7 Then the least possible number of miles that you both run to end at the same time is the least common factor of 7 and 6 minutes. This is 7 * 6 = 42 minutes. You will have run 42 min / (6 miles/min) = 7 miles, and your friend will have run 42 min / (7 miles/min) = 6 miles

The number of minutes would she take to run 9 miles will be 66 minutes.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

Answer:

Distance traveled 17.5 kilometers

Step-by-step explanation:

We can use the following equation to find the distance traveled,

Distance traveled = Speed * Time

First we need to find the total time he walked = 2.30 p.m. - 11.a.m.

                                                                             =[tex]3.5[/tex] hours

Now we can substitute the values to the equation,

Distance traveled = [tex]5[/tex] kilometers per hour * [tex]3.5[/tex] hours

                              = [tex]5*3.5[/tex] kilometers

                              = 17.5 kilometers

You haven't provided any value, but I can tell you the solution set for the inequality.

First of all, expand both sides:

[tex] -3x+12 > 6x-6 [/tex]

Add 3x to both sides:

[tex] 12 > 9x-6 [/tex]

Add 6 to both sides:

[tex] 18 > 9x [/tex]

Which is of course equivalent to

[tex] 9x < 18 [/tex]

Divide both sides by 9

[tex] x < 2 [/tex]

So, every number smaller than 2 is part of the solution of this inequality.

[tex]\frac{90 + 87 + 72 + x}{4} = 88[/tex]

90 + 87 + 72 + x = 88(4)

             249 + x = 352

                        x = 103

Answer: 103

Hey there!!

Basic formula :

... a² - b² = ( a + b ) ( a - b )

Equation given :

... 81x² - 25

... ( 9x )² - ( 5 )²

... ( 9x + 5 ) ( 9x - 5 )

Hope it helps!!

The expression 81x²-25 is a difference of squares that can be factored as (9x - 5)(9x + 5).

The given expression is 81x²-25, which is a difference of squares. The difference of squares is a special algebraic identity and it can be factored using the formula a²-b² = (a-b)(a+b). In this case, a is 9x and b is 5, because (9x)² = 81x² and 5² = 25. So, plug these values into the formula to get: 81x²-25 = (9x - 5)(9x + 5)

To factor 81x²-25, we can use the formula for the difference of squares: a² - b² = (a + b)(a - b). In this case, a is 9x and b is 5. So we have:

81x² - 25 = (9x + 5)(9x - 5)

Answer:

we cannot form a triangle using the given lengths.

Step-by-step explanation:

There are three conditions that must be satisfied in order to form a triangle.

Let's take a, b and c are the sides of a triangle.

Conditions are:

i) a + b > c

ii) b + c > a

iii) c + a > b

Here let's take a = 12.2, b = 6.0 and c = 4.2

Let's check the conditions

i) 12.2 + 6 > 4.2

18.2 > 4.2

Which is true.

ii) 6 + 4.2 > 12.2

10.2 > 12.2

Which is not true.

The condition fails.

Therefore, we cannot form a triangle using the given lengths.

Step-by-step explanation:

No : the lines have unequal slopes

Parallel lines have equal slopes

calculate the slope( m) of each line using the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 7, 2) and (x₂, y₂ ) = (7, - 6 )

m = [tex]\frac{-6-2}{7+7}[/tex] = [tex]\frac{-8}{14}[/tex] = - [tex]\frac{4}{7}[/tex]

slope of other line using

(x₁, y₁ ) = (- 1, - 5 ) and (x₂, y₂ ) = (- 3, - 1 )

m = [tex]\frac{-1+5}{-3+1}[/tex] = [tex]\frac{4}{-2}[/tex] = - 2

lines are not parallel since slopes are unequal

The lines are not parallel since the slopes of the two lines are unequal.

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

Given that the line passes through points p(-7,2) and q(7,-6) parallel to the line through points r9-1,-5) and S(-3,-1)

To calculate the slope( m) of each line using the gradient formula;

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 7, 2) and (x₂, y₂ ) = (7, - 6 )

m =  (-6 - 2)/(7+7) = -8/14

m = -4/7

Now the slope of other line using the same formula;

(x₁, y₁ ) = (- 1, - 5 ) and (x₂, y₂ ) = (- 3, - 1 )

m = (-1, +5)/ (-3, +1) = 4/-2 =  - 2

Hence, the lines are not parallel since the slopes of the two lines are unequal.

For a better understanding of the explanation given here please go through the two graphs provided in the two files attached.

In the first graph we have plotted all the given points from the question. The y-axis is the quantity and the x-axis is the price. As can be seen, as the price increases, the quantity decreases.

In the second graph, the line that connects all the given points is drawn. This line represents the "Demand" Line and is evaluated as follows:

We take any two points (in our case we took the first and the last points, that is, [tex](x_1,y_1)=(0,19)[/tex] and [tex](x_2,y_2)=(3,1)[/tex]) and we made use of the "point slope form" as:

[tex]\frac{y-y_1}{x-x_1}= \frac{y_2-y_1}{x_2-x_1}[/tex]

Answer:

The vertices of parallelogram ESTA  are E (10, 0), S (14, 3), T (6, 9), and A (2, 6).

As we know ,Area of parallelogram = Base × Height

As base can be determined by using distance formula because coordinates of the vertices are given.

Now to determine perpendicular, we will find the equation of line through E and perpendicular to ST.

Equation of line through S(14,3) and T(6,9) is

[tex]\frac{y-3}{x-14}=\frac{9-3}{6-14}\\\frac{y-3}{x-14} =\frac{6}{-8}[/tex]

[tex]\frac{y-3}{x-14}=\frac{-3}{4}\\4y -12=-3x+42[/tex]

⇒4y + 3x =12+42

⇒ 3 x + 4 y=54

Equation of line perpendicular to ST and passing through E(10,0) is

4 x-3 y + k=0

Put x=10, y=0 in above equation is

4×10 -3×0 +k=0

⇒ k= -40

The Equation of line through point E and perpendicular to ST is

4 x-3 y -40=0

Answer:

-2.67,2.07,2.67,27/10

Step-by-step explanation:

Correct answer is: A) [tex]\frac{-15F}{13hours}[/tex]

Solution:-

Given that temperature of town increased 16 Fahrenheit in 5 hours and decreases 31 Fahrenheit in the next 8 hours.

If we assume T as temperature, it became T+16 in 5 hours and (T+16-31) in next 8 hours.

That is change in temperature in (5+8) hours is 16-31 = -15 Fahrenheit.

Rate of total change in temperature = [tex]\frac{change in temperature}{time}[/tex]

                                                            = [tex]\frac{-15}{5+8}=\frac{-15}{13}[/tex]

Hence rate of total change in temperature is [tex]\frac{-15F}{13hours}[/tex]

The correct expression that shows the rate of the total change in temperature is -15 hours / 13 hours. The Option A.

The rate of change in temperature refers to the speed at which the temperature is increasing or decreasing over a given period of time.

Total change in temperature is:

= Temperature increase - Temperature decrease

= 16°F - 31°F

= -15°F

Total time for the change:

= Time for increase + Time for decrease

= 5 hours + 8 hours

= 13 hours

Rate of total change in temperature:

= Total change in temperature / Total time for the change

= -15°F / 13 hours.
